A polarizing filter. Not sure about the G5 and if you can fit them right onto the lens or not. There are people here who also own that camera... they can answer that..... The trick to using a polarizer is where you are standing in relation to the glass and then twisting the filter until the reflections disappear. Here's a link to a tutorial I did on the subject.... not as thorough as it could be, but it'll give you an idea. Then do a google search on Polarizing Filters to see if you can find anything more in-depth articles elsewhere.

I am, therefore I create.......
